an entirely new type of heated air circula tion control to effect new results. With that end in view, the invention contemplates the provision of shutters located at the side or sides of the shell or casing and which may be full closed, fully opened, or partially opene for the purpose of regulating and changing the circulation of the air and the radiation of the heat in a new manner not obtainable by the use of ordinary dampers by which the flow and volume of 'air'alo'ne is controlled as distinguished from the direction of theflow. A practical embodiment of-the invention contemplates the provision of pivotally horizontally arranged shutters, coupled together to move in unison and located on oposite sides of the shell or casing, provision eing made for control of the shutters so that their posltion may be changedat will.

When the shutters are closed all of the heated air is circulated between the outer casing or shell of the stove and the stove itself which is inclosed within the shell-or casing, such heated air passing through openings in the upper part of the shell and out into the'upper part of the room before such heated air can return to the lower part i 40 of the room. However, when the shutters are partially opened, say about halfway open, the heat from the inclosed stove or heater will radiate through the-spaces between the shutters and be" deflected downwardly toward the floor, aside from the heated air flowing upwardly within the shell and out through the openings in the top of the latter. If the shutters are fully opened there will be more 'dir'ect'radiation from the inclosed stove and toward the floor, thus radiating the heat more tosthelower part-of therooin and naturally lessen mg the volume of heated air which rises within the shell or-casing and passes out 55 throughthe openings in the top of the latter.

the shutters at theleft hand side of the shell My improvements, therefore, are readily distinguished from the ordinary damper control because the latter makes no. provision for directing radiation outwardly and downwardly from the stove, whereas with my invention such adjustment of the'shutters may be effected that the relative proportions or .volumes of radiated heat directed downwardly and directed upwardly may be regulated at wilL: v

My improvements are well adapted for use in .connection with those inclosed stoves V 4 which have an ornamental or cabinetlike exterior appearance but they may be used in connection with any inclosed stove type of heater.

In the drawings:

Figure 1 is a perspective view of a stove or heater equipped-with my improvements,

76 being present but'not a peering;

Figure-2 is a front e ovation, the shell or casing being broken away to show the stovewhich is inclosed within the shell; and

Figure 3 is a detail perspective view,- broken away, showing certain of the shutters and the frame in which they are mounted.

The metal casing or shell p ears at 1, and the stove or heater contained therein is shown at '2, said shell and stove-or heater being separated by an air space 3";for the circulation .of the heated air. The fire box door is shown at 4 and. the ash-pit door appears at 5; Theto of the shell 1 has openmgs or a grill wor 6 to permit the heat to escape therethrough.

Doors 7 are provided to. afford access to' the. stove 2 andto complete the inclosure of-the stove so that it will notbe visible.

' My invention has nothing to do with the ordinary damper control of a stove or heater such as has been heretofore proposed but, on i the contrary .the purpose is to control the I circulation of the heated air and the distri- I bution oi the heat by radiation-downwardly and outwardly, as reviously set forth. y

- Both sides of t e shell or casing 1;are providedwith shutters'S which are mounted so that they ma be completely closed, partly o ened, or fu y opened. Preferably, the s uttersare carried by-a frame 9 to which the y are pivoted in any suitable manner at bot of their ends as shown at 10. By mounting the shutters 8 in a frame .9, the 1 entire shutter arrangement may be assembled separably from the stove and installed on the stove as aunit. It will be understood,

however, that the shutters 8 may be directly.

the will of the user of the stove, so that,

all of them will be arranged at the same angle.

y preference the shutters 8 have a flange .15 to'enable them. to be tightly closed together and for the purpose of strengthening them and preventing buckling.

The shutters 8 and the frame 9 are of sheet metal of suitable gage.

The side walls of the shell or casing 1 are provided with openings into which the frames '9 are set, said frames then being secured to the shell or casing 1 in any desired manner.

As previously set forth, when the shutters 8 are closed, they form, in effect, a

closed side wall fbr the shell 1-. The heated air then circulates between the shell and the stove 2, passing out through the openings 6 and rising to the top of the room before returning to the lower part of the latter.

When the shutters 8 are partially opened, that is, about half of the way, as shown for instance in Figure 1, the heat from the stove 2 will radiate through the spaces between the shutters and be deflected by the shutters down towards the floor, while heated air flows upwardly within the shell and out through the openings 6 in top grill.

When the shutters are fully opened as shown in Figure 3, for instance, there will be a more dlrect radiation from the stove through the openings between the shutters and down toward the floor so that a lesser amount of heated air will flow upwardly between the shell 1 and the heater 2.

Thus, the user, by setting the shutters 8 in different positions, may vary the circula tion of the heated air and also the radiation of the heat, according to requirements.

It is to be understood that in the use of the words shutter or shutters -in the claims, I do not limit myself to the specific construction and arrangement of shutters hereinbefore described and which are shown in the drawings, nor is the invention limited to disposing the shutters on the sides the shell or cas' nor to their use on both sides of said she maaesa I claim:

1. The combination with a stove or heater, of an inclosing shell or casing therefor, and regulable means carried by said shell whereby the heat within said shell may be ra diated outwardly from the shell in di-fi'erent predetermined directions according to the setting of said regulable means.

2. The combination with a stove or heater, of an inclosin shell or casing therefor, and regulable de ectors carried by said shell whereby the heat within said shell may be radiated outwardly from the shell in different predetermined directions according to the setting-of said deflectors.

3. The combination with a stoveor heater, of an inclosing shell or casing therefor, and regulable means carried by said shell adapt ed for radiating the heat from within the shell outwardly and downwardly in relation to the shell in different predetermined directions according to the setting of said regulable means.

4. The combination with a stove or heater, of a shell or casing therefor, and controllable deflectors adapted to be set in different positions to radiate the heat from within the shell o'utwardly therefrom in different predetermined directions, according to the setting of said deflectors, said deflectors being also adapted to be closed to limit the radiation.

5. The combination'with a stove or heater of an inclosing shell or casing therefor, an swingingly mounted shutters carried by said shell which are adapted to be closed or to be set indifferent open positions, wherebv the heat may be prevented from radiating past said'shutters, or, may be radiated outwardly,

-01 downwardly, from said shell in different predetermined directions according to the settingof said shutters.

6. The combination with a stove or heater, of an inclosing shell or casing therefor, said shell having in an upright wall thereof a group of connected, pivoted, horizontally arranged, shutters which may be closed, or, opened to assume different angles whereby the heat maybe radiated from said shell past said shutters in different predetermined directions according to a setting of said shutters.

7. The combination with a stove or heater, of an inclosing shell or casing therefor, and regulable means carried by said shell whereb the heat within said shell may be ra-- diated outwardly from the shell to different extents according to the setting of said regulable means. 1

8. The combination with a stove or heater, of an inclosing shell or casing therefor, and regulable means carried by, said shell whereb the heat within said shell may be radiated outwardly from the shell to diiferent extents according to the setting of said regadapted for'exercising ulable means, and the circulation of the heated air within the shell or casing may also be varied.

9. The combination with a stove or heater, of an inclosing shell or casing therefor, there being an air space between the stove or heater and the shell or "casing, and regulable means carried by the shell or casing a joint or combined control over the radiation from the heater into the room 'it occupies and onthe rising aircurre ts in the-air space aforesaidor heater and 10. The combination with a stoveor heater, of an inclosing shellor casing therefor,

there beingan air space between the stove the shell or casing,. and a regulating set of shutters acting as combined air shutters and refiectors, whereby common or joint control may be exercised over the radiation from the heater into the room it occupies and on the rising air currents in the air space aforesaid.

In testimony whereof I afiix my signature.
